B. The total cost depends on the number of roses purchased.
Two of butterflies, side by side, would be abot 7.4 together. 8.2 - 7.4 = 0.8.
that 0.8 is roughly 1/3 of a butterfly. so 2 full butterflies and 1/3. rounding off, it would just be two butterflies.
The answer should be 39/400
Hi!
<h3>Let's use the guess and check method. </h3><h3>First, find numbers that when divided, equal 4, and are less than 20. </h3>
- 4/1 = 4
- 8/2 = 4
- 12/3 = 4
- 16/4 = 4
<h3>Now see if any of those pairs of numbers add up to 20. </h3>
- 4 + 1 = 5
- 8 + 2 = 10
- 12 + 3 = 15
- <u>16 + 4 = 20</u>
<h2>The answer is 16 and 4.</h2>
Hope this helps! :)

Answer:
the number of men be 56
And, the number of women be 74
Step-by-step explanation:
The computation of the number of each genders attended the conference is shown below;
Let us assume the number of men be x
And, the number of women be y
Now the equations would be
x + y = 130 .............. (1)
And,
y = 18 + x ................ (2)
Now put the y value in the equation 1
x + 18 + x = 130
2x = 130 - 18
2x = 112
x = 56
Now the y is
= 18 + 56
= 74
So, the number of men be 56
And, the number of women be 74
